Objectives of studying the discipline |
the formation of the fundamentals of mathematical thinking among students, familiarity with the methods of mathematical proofs, the construction of geometric models using the concept of convexity and analytical models and problems in which convex functions and concepts close to them participate, as well as the study of algorithms for solving specific mathematical problems associated with the notion of convexity. As a result of studying the discipline, the trainee must: be able to: – find solutions to problems on convex sets and convex functions; – independently to orient in the literature on the subject convex sets and convex functions. |
